Abstract

The invention discloses an improved structure of a clamping device. The clamping device comprises an outer ring and an inner ring, the inner ring is located in the outer ring, and the outer ring and the inner ring are concentric rings. The outer ring and the inner ring are fixedly connected through connecting rods. The inner ring is provided with at least one threaded through hole, and a bolt is arranged in each threaded through hole in a matched mode. The outer ring is provided with a through hole, one end of a cover plate is hinged to the inner wall of the through hole, a protruding piece is arranged at the other end of the cover plate and provided with a fixing through hole, the outer ring is provided with a groove matched with the protruding piece, and a threaded hole matched with the fixing through hole is formed in the bottom of the groove. The cover plate is fixed to the outer ring through matching of a bolt I and the threaded hole, and the through hole corresponds to the bolts. By means of the improved structure of the clamping device, the problem that an existing clamping structure is not convenient to operate.

Description

technical field [0001] The invention relates to a petroleum mechanical processing device, in particular to an improved structure of a clamping device. Background technique [0002] In the process of oil extraction, the drill pipe is an indispensable tool. The drill pipe can be used repeatedly. In order to improve the service life of the drill pipe, the drill pipe must be maintained and cleaned after each use. During the use of the drill pipe, the mud, stone chips, oil stains and other debris generated by drilling will adhere to the outer wall of the drill pipe, corrode the outer wall of the drill pipe, affect the service life of the drill pipe, and damage the drill pipe. The next use will be affected, and the drill pipe with debris attached will affect the quality and work efficiency of the next drilling. Therefore, the drill pipe must be cleaned after use. [0003] Due to the long length of the drill pipe used in petroleum machinery, due to gravity, the middle part of the ...
